Graphite paddle mashers?
I'm after a pair of simple mashers with 2x2" or so graphite paddles. Like item 'P-MASFW53' here http://www.crloo.com/Products/Hand_T..._tools_10.html. I emailed this shop but they're out of stock with no ETA... So has anyone seen something similar somewhere else, besides the more expensive 'true parallel' ones from ABR and Whale?
...though the 'true parallel' ones do look nice...

Glue hey? Neat idea... What kind of glue would adhere to graphite?

Well this is what I have so far... no glue used yet, as I have no idea what kind of glue to use. The screws just don't hold very well, if at all, due to them stripping the graphite holes.
I have E6000 but it says to not heat it up at all... And epoxy breaks down with heat too... And, well most other glues. I don't even know if they'd stick to the graphite in the first place! So any suggestions for a suitable glue?

Wow that's some cool sounding stuff! Or 'hot' sounding stuff...  But at that price I'd be better off buying one of the ABR or Whale parallel presses anyway lol (which I may do anyway even if I get my own pair working, they look fun!)
My Dad said oven/stove-top ceramic cement could be good though, so I'll be trying that hopefully tomorrow.

Personally, I use the end of my marble mold and my torch mounted marver to mash stuff.

Yeah I'd normally do that too (that was an unexpected plus when I first got my 'regular' marble mold lol), but I need these for a more delicate and precise operation, in which the 'width' axis needs to be parallel at least

super glue will bond graphite to metal.
It's flash point is around 450 - 500 degrees.
Melting point is around 5 seconds in the torch flame (sigh, I don't know the temp. lol).

Oh thanks for that Donna. I'm surprised it holds up so well in the flame! I guess I might as well try super glue first then, worst thing that happens is the glue does fail, so I just try the ceramic one anyway...

It's to roll glass rods between the two pads, so the molten end of the rod gets squished down to the same round diameter as the cold rod. Steel is a bit too rough I find and tends to turn the glass 'frosty'...

metal is best for 'grabbing' glass, graphite is smother for a rolling action.

What if you kept the metal mashers rubbed with beeswax, like furnace workers do?

Roy,
I have used wax on my tools once and only one tool, as it was highly suggested at the time to use it for this type of rolling brass tool that I bought.
I will say it did help this odd shaped tool a bit, so I thought that I would try it on some of my other brass and metal tools.
I too have enjoyed working in a friends hot shop and saw them use the wax so hey why not try it???
I spent months picking wax off my tools, smacking myself in the head for doing it, without further testing. It seemed like a good idea until I tried it on other tools like presses and mashers, etc.
The shapes and designs of the tools had a lot to do with how well the wax worked; rolling hot glass onto a tool is perfect for wax, but in an enclosed area, in my experience it failed.
